The intramolecular fluorescence quenching efficiency of <I>p</I>-nitrophenyl and <I>p</I>-nitrophenoxy groups in homologous series of <I>p</I>-O<SUB>2</SUB>NC<SUB>6</SUB>H<SUB>4</SUB>(CH<SUB>2</SUB>)<I><SUB>n</SUB></I>NH-1-Naphthyl (I, <I>n</I>=1–7) and <I>p</I>-O<SUB>2</SUB>NC<SUB>6</SUB>H<SUB>4</SUB>O(CH<SUB>2</SUB>)<I><SUB>n</SUB></I>NH-1-Naphthyl (II, <I>n</I>=2–6), respectively, has been determined. The quenching effect is observed even in the highest homologs of both series. From the fact that the fluorescence intensity of <I>n</I>=2 homolog of I is higher than that of <I>n</I>=1, together with spectroscopic data it is concluded that the higher intensity of <I>n</I>=2 than <I>n</I>=1 of the across-space intramolecular charge-transfer band is due to the larger absorbance per interacting molecule of <I>n</I>=2, the origin of which might be attributed to the different interacting conformations of these homologs. The effect of the number of methylene groups (<I>n</I>) on the fluorescence spectral shape has also been found.
